Buildroot Developers Meeting, 3-4 October 2015, Dublin

Location and date

The Buildroot community is organizing a meeting on October 3rd and 4th 2015, for Buildroot developers and contributors. This meeting will be a mixture of discussion and hacking session around the Buildroot project. This meeting takes place right before the Embedded Linux Conference Europe, in order to make it easy for participants to attend both events. It is not mandatory to attend both days.

The meeting will take place in the Orange Business Services offices, located:

Garryard House
Earlsfort Terrace
Dublin 2


We are currently looking for companies willing to sponsor the event. The sponsoring will be used to pay for the Saturday dinner for the participants or Buildroot T-shirts for the participants. Contributions in the range of 250 EUR to 500 EUR are sufficient.

Registration now closed.

Who can attend ?

This meeting is opened to all Buildroot users and developers. The event is free. However, we make it clear that it is not a training event about Buildroot aimed at newcomers. It is a meeting for Buildroot developers to make progress about various topics in Buildroot. It is recommended to already be a Buildroot contributor to participate to the event.

For administrative reasons, participants will have to register to the event before Friday, Sep. 25th, so that access badges are printed. For this reason, people that are not registered will not be granted access to the site. Please, register by adding your name to the list, above. Registration now closed.
